Continuous casting copper disc (99.95% pure), macro etched, ∅ ≈83 mm, by Heinrich Pniok.

Well, what’s left of August is Metals Month, I should say. A broad subject, to be sure, and with only a couple of weeks to explore it, I want to be fairly strict about focusing on interesting and unusual metals themselves (and processes for working with them) rather than more general “cool stuff made from metal.”  Even limiting the scope this way, our archives are rich with relevant content, and my first priority is to round up the best of it.  Look for that tomorrow, and in the meantime, as always, if you have suggestions for subjects you’d like us to cover, under this banner, please let us know below.
